Specification of Letters Patent.

Application filed August 27, 1908. Serial No. 450,406.

To all whom it may concern:

Be it known that 1, WILLIAM E. WooDAnn,

- The improvement claimed is hereinafter fully set forth.

ln the accompanying drawings: Figure 1 is a plan or top -view, partly'in section, of a car truck embodying my invention; Fig. 2, a side view,in elevation, of the same; Fig. 3,, a-half transverse central section;and, Fig. 4, a half transverse section in the plane of one of the axles.

In the practice of my invention, I provide a truck frame having two sidemembers, each of which isan integral metal plate, and comprises a topbar, 1, a bottom bar orpedestal tie bar, 1", and pedcstaljaws, 5, saidside members being connected one to the other, on opposite sides of thetransverse central plane of the truck, by two transoms, 2, which, in theinstance shown, are of channel section, but may be of any other suitableand preferred form. to the side members through the intermediation of'lilling castings, 3, the webs of which are bolted to the side members,and which have lateral flanges bolted to the transoms. The transoms andside members are also connected by gussots, 4, secured to them byvertical and horizontal bolts, the. connections being preferably, asshown, made through the intormediation of angles, 1", which serve,further, to stiil'en the side members.

Journal box guides or pedestal wear shoes, are bolted to the outer sidesof each pair of pedestal jaws, 5, between which guides are iitted thejournal boxes, 9, which inclose the bearings, S), for the journals, 8,of the axles, 8, on which the wheels, 7, of the truck, are secured. Thejournal box guides, extend through the openings between the pedestaljaws, and project from the outer sides there of practically throughouttheir entire width or transverse d1mens1on, their projection from the111 nor sides of the side members be- The transoms are secured ing onlyfor the slight extent which ivill suflice to enable the inner flanges ofthe j ournal boxes to clear them, and the frame side members, 1, aretherefore located in vertical planes inside of, or nearer to thelongitudinal central plane of the truck than, the vertical centralplanes of the journals, 8. The truck frame is movable vertically,relatively to the journal boxes, on which each of its side members is suported by a single equalizer, 10. The equllizers, 10, are straight bars,of rectangular section, which extend longitudinally adjacent to theouter sides of the side members, 1, from one'of the journal boxes ofeach side member to the other, their vertical planes being in or nearthe vertical central planes of the journals, 8, and their ends restingon the tops of the journal boxes.

The side members are supported on the I equalizers through theintermediation of helical equalizer s rings, 11, which are coiled.around springro s, 12, suspended, at their upper ends, on, and dependingfrom, the equalizers, said e ualizer springs abutting, at their lower ens, on spring seats, 12, fitted on the spring rods, and, at their upperends, on spring sea-ts, 12 bolted to the adjacent side member, below theequalizer, through upwardly and downwardly extending lateral flanges.

A spring plank, 13, is suspended from the transoms, 2, by swing hangers,14, journaled .on swing hanger pivots, 15, which are fitted in swinghanger pivot bearings, 16, on'the tops of the transoms. A swing bolster,17, which, in this'instance, is shown as of U or channel section, andhaving its vertical members stiffened by angles, 17, but which may be ofany other preferred form, is su )orted on the spring plank bysemi-elliptic olster springs, 19, two pairs of which are interposedbetween the spriiw lank and seats, 17*, located near each of t 1e endsof the bolster. The webs of the filling castin s, 3, of the transoms,serve as end stops for t 1e bolster and wear plates for the adjacentends thereof. Acenter casting, 20, and side bearings, 21, of theordinary form, are secured to the bolster, at the middle and ends,respectively.

The form and relation of the side members and edestals above describedare such aseto simp ify the construction and minimize the enablingsingle straight equalizers to be applied, instead of pairs of equalizershaving upwardly bent ends, as heretofore employed, and, by reason of theframe construction used, necessary in, trucks of the M. C. B. type. Theforgings for equalizers of the latter form are more complicated anddiflicult to make, and are subject to the risk of injury in bending,from which the straight equalizers are entirely exempt.

I claim as my invention and desire to secure b Letters Paten In a cartruck, the combination of two plate metal side frame members, havingpairs of integral pedestal jaws adjacent to their ends, journal boxguides fixed to and projecting, for the major portion of theirtransverse dimension, from the outer sides of the pedestal jaws, axlesjournaled in jour- .nal boxes fitting between said journal box guides,wheels fixed on said axles, transoms interposed between the side framemembers on opposite sides of the transverse central plane of the truck,filling castings bolted to the side frame members and to the transomsbetween the ends of the latter, angle plates secured to the side framemembers and extending from the transoms to the pedestal jaws, gussetssecured to said angle plates and to the transon'is, single straight barequalizers supported on the axles exterior to the side frame members,and equalizer springs interposed between and bearing on said equalizersand the side frame members.
